Streetcars are on their way back to the District, but many questions remain unanswered.
D.C. officials say they are hopeful the city's new streetcar system will be up and running by the end of the year.
"We will have the cars on the track. We have to go through the certification through federal government and state oversight," says DDOT Director Terry Bellamy. "Once they tell us we can go live, we will go live."
Asked what the odds are that the streetcars will go live before 2014, Bellamy said it was about a 2 in 3 chance.
The first stretch of track will be a 2-mile line along H Street and Benning Road in northeast.
The city received the cars earlier this year and is now testing them, but key questions remain. Namely, how much will it cost to ride and how passengers will pay?
